Item #: 70117239Brand: DeWALT Model #: DAAH7GPW05Exact Tooling IR#: 04 Features and Benefits Non-Woven abrasives reduce undercutting and gouging of surfaces. They are frequently used in deburring, surface preparation and as a final finishing step. Type 27 flap discs are less aggressive and are used primarily on flat surfaces for grinding a smoother finish. Aluminum oxide is the most commonly used abrasive. Best-suited for general purpose deburring and blending, it is tough, economical and fracture resistant. Commonly used on ferrous alloys, high tensile materials and wood. Arbors require adapting nuts. They eliminates cross threading.
